Specification of Letters Patent. Patented Apr. 27, 1915..

Application filed March 25, 1912. SeriaI No. 686,056.

To all whom it may concern Be it known that I, SAMUEL T. HOBBS, a citizen of the United States, residing at Worcester, in the county of Worcester and Commonwealth of Massachusetts, have invented a new and useful Improvement in Box-Ending Machines, of which the following is a specification, accompanied by drawings forming a part of the same.

My invention relates to that class of box ending machines designed for the'manufacture of paper or cardboard boxes, comprising means for the pasting andapplication of a cardboard end to a flanged box body.

The objects-of my invention are to facilitate the adjustment of different parts of the machine to accommodate boxes of different sizes, andto provide certain safety devices for controlling the operation of the machine as hereinafter described.

These objects, among others, I accomplish by the construction and arrangement of parts as hereinafter described, the novel features being pointed out in the annexed claims.

Referring to the drawings, Figure 1 represents a front elevation of a boxending machine embodying my present invention. Fig. 2 is a side elevation. Fig. 3 is a vertical sectional view of the upper part of the machine, showing the pasters in their posi tion just before the pasting operation. Fig. is a detached top viewof the box form. Fig. 5 is a rear elevation of the upper part of the machine, showing the pasting mechanism in the position which it occupies during the middle of its movement. Fig. 6 is a detail view of a portion of the mechanism for adjusting simultaneously the positions of different parts of the machine to accommodate them to the manufacture of boxes of different sizes, part of the figure being shown. in section to illustrate the geared connection by which the pasters are adjusted. Fig. 7 is a perspective view of the box body. Fig. '7" is a plan view of a box-end adapted to be applied to the flanged end of the box body shown in Fig. 7 Fig. 8 is a detached view, partly in section, showing a portion of the driving mechanism for imparting an intermittent rotary motion to the pasters.

Similar reference characters refer to similar parts in the different figures.

The box ending machine embodying my present invention comprises two upright side frames 1, 1 united at the top by a transverse plate 2 forming a platen toward which the box form is moved in the operation of stick ing the box end to the body of the box. Sliding in ways 3, 3 on the uprights 1 is a frame l, to which a vertically reciprocating motion is imparted by means of eccentrics5 on the. opposite ends of a shaft 6. One of these eccentrics is shown in Fig. 2 and they are j ournaled in boxes 7 capable of a slight sliding movement in ways 8, 8 in links 9, which are pivoted at their upper ends to gudgeons 10, 10 held by the vertically reciprocating frame 4. The links 9 are provided with cross bars 11, between which and the tops of the boxes 7 I interpose spiral springs 12 having their lower ends centered upon studs projecting from the boxes 7 and their upper ends centered uponsimilar studs projecting from blocks 13, capable of, a slight sliding movement in ways 14, 14.- in the links. 7

Held in the cross bars 11 and bearing against the blocks 13 are set screws 15, which may be screwed down to further compress the springs andincrease their tension. The springs 12 form a yielding element between the pressing mechanism and the actuating eccentrics 5 as the pressure exerted is transmitted through the springs. The vertically reciprocating frame 4 is provided with ways 16, on which brackets 17, 17 are capable of sliding in order to adjust their distance apart for different size boxes. The upper ends of the brackets 17, 17 are provided with pressing surfaces 18, 18, Fig. 4,,0n which the side flanges of the box body rest. De-

tachably held upon the brackets 17, 17 are plates 19 and 20 overlapping each other at their central sections and clamped together by a bolt 21 and nut 22, said bolt passing through a slot in one of the plates to permit the combined length of the plates to be varied, The plates 19 and 20 have their upper surfaces 23 and 24 flushrwith the surfaces 18 and constitute the pressing surface for the bottom flange of the box body. The upper ends of the brackets 17 together with the front plates 19 and 20 constitute the box form upon which the boxbody is supported during the operation of applying a box end thereto. j j V The box body shown in perspective View in Fi ."7 is applied to the box form with the side anges 25, 25 resting upon the surfaces 18 of the box form, and the bottom flange 26 resting uponthe upper surface of the front plates'19 and 20.

When a rectangular pasted box end has been placed in proper position beneath the platen 2, it is pressed firmly against the flanges of the box body bythe upward movement of'the box form against the platen 2. The box ends, consisting of rectangular pieces of cardboard, are held'in a vertical stack 27 mounted onthe top of the machine,

formed of a vertical front plate 28, a rear plate 29 and a pair of side plates 30, 30. The rear plate 29 isattached to a'slide 31, adjustably held by a clamping screw 32 on the top plate of the machine.

one direction o-r the other, the distance be-" tween the brackets 17 is varied to suit the i different widths of box bodies, the plates 19 and 20' being likewise adjustable to. correspend with the adjustment of the brackets .35 I

17, 17. 7 V f The box ends 41 held in the stack 27 are supported upon the inwardly turned lips at i the lower ends of the sides of the stack, two

such supporting lips being shown'at 42, 42, Fig. 1. Sliding in ways in the top plate of s the machine are racks 43, 43. The rear ends of the racks 43, '43 are connected by a cross bar 44.- Attached to the vcenter of' the cross bar 44 and extending toward the front of the machine 'is the box ,end transferring device comprising a narrow plate or carrier 45 and a pusher plate 46. As the plates 45- and 46 move forward toward the front of the machine, the lower box end in the stack 27 is pushed forwardout of the stack by the pusher plate 46 and, supported upon the carrier 45, is moved forward into registration'with't'he box body held upon the box form in the usual manner in box ending machines.

The racks 4 3, 43 are engaged by pinions 47, 47 on a transverse .shaft which carries upon one end a gear '48 engaging a gear 49 attached to a sleeve 50 journaled in a bearing upon the framework of the machine and shown in sectional view in Fig. 8. The.

sleeve '50 is provided at one endwith a pin- "ion 51 and at its opposite end it carries a pawl 52, held by a spring in the usual manner in engagement with a ratchet wheel 53 which is provided with a hub 54 attached to a short shaft 55. The shaft 55 extends through the sleeve 50 and it carries upon its outer end a hand wheel 56. The shaft 55 is inclosed in a bearing 57 held in a bracket 58,

Fig. 1, attached to the framework of the machine. The inner end of the shaft 55 does not extend quite through the hub 54 and its end is provided with a diametrical slot 59 to receive a tongue 60 on the end of a shaft 61 to which the pasters are attached.

The pinion 51 is engaged by the teeth of a rack bar 52 which is held in engagement with the pinion by means of a housing 63. The rack bar 62 is pivotally connected at its lower end with the arm 64 of a two-armed lever pivotally supported on the framework of the machine, the other arm 65 of the lever carrying a cam roll 66 engaging the grooved side of a cam 67 arranged to give a reciproeating movement to the rack bar 62 and 7 through its connection with the gear 48 impart a rotary movement in both directions to the pinions 47, 47 in order to reciprocate the racks 43, 43.

By means of the pawl and ratchet mechanism between the sleeve 50 and the shaft 61, an intermittent rotary motion will be imparted in one direction to the shaft 61 by which the pasting devices are rotated for the purpose of applying paste to the box end as it is being pushed forward from the stack 27. The pasters carried by the shaft 61 comprise a bar 68 having at its lower end arms 69, 69 attached to the paster shaft 61 and adapted to apply paste to the front edge of the box end. The shaft 61 also carries a pair of segmental disks 70, 70 adapted, as they are rotated, to apply paste to the side edges of the box end. The rotation of the pasters 68 and 70 carries them into contact with the periphery of a gum roll 71 running partially immersed in gum, or other adhesive material, held in a gum box 72. The

curved or segmental pasters 70, 70 are slidable on the shaft 61 and are connected together by a screw 73 having a right and left hand screw thread capable of being rotated to vary the distance between the pasters 70, 70. The screw 73 is journaled in the arms 69, 69 and also in a hub 74 of a spur gear 75 which is attached to one end of the paster shaft 61.

' The gear 75 engages a gear 76 on the shaft of the gum roll 71, causing an intermittent motion to be imparted to the gum roll 71 corresponding to the intermittent motion of the shaft 61 carrying the straight bar paster 68 and the segmental pasters 70, 70 which are arranged to pass in contact with the gum roll 71 to receive gum therefrom during each revolution. J ournaled in the end of the paster shaft 61 is a short spindle 77, Fig. 6, carrying on its outer end a pinion 78 in permanent engagementwith' a pinion 79 on the end of the right and left hand screw 73. The teeth of the pinion. 78 overhang the teeth'of the pinion 79 to allow a pinion 80 attached to the end of a slidable shaft 81 journaled in a bracket attached to the framework of the machine to be moved into engagement with the pinion 78 by a crank handle 82. The shaft 81 is capable of being moved longitudinally in its bearings in order to push the pinion 80 into engagement with the pinion 78 to enable rotary motion to be imparted to the right and left hand screw 73 by the rotation of the crank handle 82, in order to vary the distance between. the segmental pasters 70, 7 0 tocorrespond with the width of the box ends 11.

The outer end of the pinion 78 is provided with a conical recess to enable it to be supported upon a tapering center 83, capable of sliding in its bearing in the framework of the machine in order to withdraw the center from the pinion 78, thereby releasing the paster shaft 61 and the screw 7 3 to enable them to be withdrawn from the machine. The center 83 is held in place by means of a. clamping screw 8% passing through a slot 85 in the framework and provided with a hand wheel 86, arranged to bear against the framework and clamp the center in position as the screw is tightened. V

The shaft 81 carries a pair of sprocket wheels 87 and 88. The sprocket wheel 87 is connected by a chain belt 89 with a sprocket.

wheel 90 on the right and left hand screw threaded shaft. 35. The sprocket wheel 88 is connected by a chain belt 91 with a sprocket wheel 92 on the right and left hand screw threaded shaft 410. The sprocket wheels 90 and 92 are capable of turning loosely on their respective shafts 35 and 4.0 and are connected therewith by clutches 93 and 94, arranged to be operated in order to temporarily disconnect either the shaft 35 or the shaft 10 from being rotated by the rotation of the shaft 81. These clutches 93 and 94: are, however, normally in engagement so that the rotation of the shaft 81 by the crank handle 82 will rotate simultaneously the screws 73, 35 and 40, causing the distance to be simultaneously varied between the segmental pasters 7 O, 7 0, the sides 30, 30, of the stack, and the brackets 17, 17 supporting the sides of the box form. The clutch connections provided on the screws/73, 35 and 40 enable each one tobe adjusted in correspondence with the others. After being so adjusted, the rotation of the crank handle 82 will simultaneously vary thedistance between the sides 30, 30 of the stack to fit larger or smaller box ends and, at the same time, shift the segmental pasters70, to correspond with the differentwidths of box ends and also, after loosening the clamping bolt 21 of the plates 19and 20, vary the distance between the brackets 17, 17 so that the stack, box form and pasters will always be maintained in correspondence with each other. r a

The shaft 81 carries a toothed wheel 95 which is normally engaged by pawls 96 pivoted upon the framework and arranged to fall by gravity between the teeth of the wheel 95 and hold the latter from rotation except when the pawls 96 are raised out of engagement with the teeth of the wheel 95 or when the shaft 81 is pushed lengthwise to bring the pinion 80 into mesh with the pinion 78 When the shaft has been so moved lengthwise in order to rotate the three screws 73, 35 and 40, it will be pushed back into its normal position, as shown in Fig. 6, by means of a cam 97 carried on the gear 7 5 which, by the rotation of the gear, is brought into contact with the end 98 of a sliding rod 99 held in a bearing 100 on the framework and provided with a pin 101 overlapping the edge of the toothed wheel 95. The action of the cam 97 in sliding the rod 99 pushes the wheel 95 and its attached shaft 81 outwardly into their normal position, shown in Fig. 6, and in position to be again locked from rotation by the pawls 96. The front plates 19 and 20 of the box form are attached to the brackets by screws 102, 102, enabling them to be removed and others substituted when desired.

In order to check the momentum of the pasters and maintain them in registration with the movement of the box ends,Iapply to the ratchet wheel 53 a steel brake band 103, having its ends brought together and attached to a rocking spindle 10% journaled in a bracket on the framework of the machine. The brake band 103 is so attached to the rocking spindle 104:, as represented in Fig. 3, that the rotation of the spindle will wind up the ends of the brake band and tighten it on the periphery of the ratchet wheel 53. In the normal position of the brake band the ratchet wheel 53 is free to rotate, but when the actuating rack 62 has reached its highest position, a stud 106, Fig. 5, adjustably attached to the reciprocating rack bar 62 is brought into contact with an arm 105 on the rocking spindle 104, thereby imparting a rocking movement'to the spindle in order to 7 wind up the brake band and tighten its grip upon the periphery of the ratchet wheel 53, thereby checking the rotary movement of the ratchet wheel and its connected paster shaft 61.
